Current Electric hand cart mostly on the market is four-wheel flat-plate trolley and four-wheel cell body trolley.Although four-wheel electric trolley almost instead of manpower with electric power on power, but it depends on the operation of user to buttons such as advancing, retreat, accelerate, slow down, turn to, this adds operation easier undoubtedly, especially for person in middle and old age user, study uses the difficulty of this type of tool equipment to strengthen.Meanwhile, four-wheel electric trolley needs to produce differential by button control two side drive wheel, thus reaches the object turned to.New Electric hand cart can make important improvement from simplification control operation aspect.
The control section of existing four-wheel electric trolley, drive part multidigit in dull and stereotyped bottom or cell body bottom, ground proximity.This design is not suitable for abrupt slope, cheats the non-regular road surfaces such as recessed, in intricately type, easily damages the motor be installed on below car body and controller.
Two take turns Electric hand cart turns to rapidly, simple to operate, and its heeling condition when transporting goods avoids drive part and ground too to press close to, thus plays the effect of protection motor, power supply.
Electric hand cart is on the market all operated by button control, for the user, namely top quality control pay the operation the same with pure Manual hand-push car, but eliminates the manpower that Electric hand cart is saved, so new product should make substantial improvements from control mode.
Described by this patent is a kind of haulage car based on intelligent power-assisted mode, for existing Electric hand cart on the market, on housing construction with in control mode, has made important improvement.
